IMPROVEMENT IN SAWING-MACHINES.

Specication forming part of Letters Patent No. 54,608, dated May 8,1866.

Be it known that we, ANTON SAUE and AL- BERT B. CoLToN, of Franklin, inthe county of Johnson andV State of Indiana, have invented an ImprovedMachine forSawing Cord or Stove Wood from the Log, and other similarpurposes; and we do hereby declare that the following is a full, clear,and exact description of the same, reference being had to theaccompanying drawings, made part of this specification, in which-Figurel is a side elevation. Fig. 2 is a plan of the machine. Fig. is adetached view of the counter-bar. Fig. 4 is an end view of thecounter-bar, and Fig. 5 is a section ot' the counter-bar and guide.

In the different figures the same letters refer to identical parts.

A is the main frame, to which the machinery is attached. B is thedriving-shaft, driven by steam or any other power. C is the fly-wheel,to which a wrist-pin is attached, to which is fastened by ordinarymechanism the pitman D, which operates thejsaw-slide Gr, to which isfirmly attached the muley saw K. This saw-slide works on the slides Fand F, which have beveled edges, as shown in Fig. 5, fitting intocorresponding projections on the saw-slide Gr.

The slides F and` F are firmly attached to the counter-bar E. They areinclined to the center line of the counter-bar, being elevated at theend nearest the saw, The slide F, which is nearest the y-wheel, hasabout twice as many degrees of elevation as has the 4slide F. The slideF has this inclination given to it to produce a rocking motion in thesaw; but it has been found in practice that it also communicates avertical oscillation to the end of' the counter-bar. This is however, inour improved machine, corrected by setting the slide F not horizontalnor parallel with the slide F, but on an inclination with about one-halfVot that of F as compared with the middle line of the counter-bar E.

Upon the outer extremity of the counter-bar E is attached the guide I,which is shaped as shown in Fig. 4. The upper portion of this guide,

which receives the back of the saw, tits closely' to the saw, affordingonly the necessary play to avoid friction and heating, while the lowerportion of the guide is made wide enough to give ample room for theteeth of the saw to play through it without coming in contact with it.

The saw isbrought into action and carried through the log by means ofthe toggle-joint M and the lever L, which is operated by hand. Thislever L is firmly united to the lower portion of the toggle-joint,forming with it a bellcrank.

By raising the end of the lever L the saw is brought down upon andthrough the log. The changes in position are shown by the red lines inFig. 1.

To the lever L is attached the rod N, which controls the brake O,applied to the rim ofthe {Iy-Wheel. By this arrangement, as the lever isbrought down the saw is raised out of the Wood, and at the same time thebrake is applied to the fly-wheel, thus controlling the excessive motionof the saw when not encountering the resistance of the wood.

The standard H, upon which the counterbar E slides freely, controls itlaterally.

Having thus fully explained the nature of our improvements, what weclaim as our invention, and seek "to secure by Letters Patent, is Y l.The guide I, formed as described, when attached permanently to the endof the counter-bar E, substantially in the manner and for the purposeset forth.

2. Raising and lowering the counter-bar E and saw K by means of a toggle-joint, M, and hand-lever L, the whole being arranged to operatesubstantially as set forth.

3. The combination of the brake O, rod N, and lever L with thetoggle-joint M, for the purpose of bringing the brake O into action onthe ily-wheel by the same movement that raises the saw, substantially inthe manner set forth.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.

ANTON SAUR. ALBERT B. OOLTON.
